Considerable movement <br /> takes place along the hose while the fill elbow is connected . Walk-downs and changes from one <br /> compartment to another move the hose across the pavement, rotating the elbow along with it. <br /> I The result can be a loosening of the adaptor. As the adaptor backs off, the seal between it and <br /> the nipple is relaxed and a leak path is created allowing vapors to escape to the atmosphere. <br /> Vacuum-assist dispensing systems can aggravate this situation due to the slight pressurization <br /> %Now* of the UST. <br /> The 61 SA Swivel Adaptor mates with 4 " top-seal delivery elbows and features a top section <br /> 61SALP- 1020-EVR that rotates with hose movement while the bottom section remains securely in place <br /> maintaining seal integrity. <br /> Features <br /> 40� Dual Seals – ensure a vapor and • Same Internal Dimension as <br /> liquid-tight seal .
